Software Design : Software Development Life Cycle

1. (B) An analysis of proposed system feasibility and a logical system design are part of which of the following SDLC phase? a. Construction phase b. Definition phase c. Implementation phase d. System-building phase

A: In the software lifecycle there are 4 phases that are derived from the old System Development Life Cycle (SDLC) and they are as follow; Planning, Implementation, Maintenance, and the Removal process. The planning phase is defined by all planning activities including the analysis of the software to be installed, verification of its compatibility, supported methods of installations, and the identification of any risks associated with the software and the desired deployment method. The Implementation phase is used to prepare for deployment such as; creating a shared access location for files and creating or using the appropriate package files. After all these steps have been

System testing will help identify if normal or incorrect actions in the program are working correctly because every line of the program code should be able to execute test errors messages.

As the world became more and more dependent on technology with each passing day, software automatically became an important organ for development. Since software is needed almost everywhere today, its development is a highly intelligent and precise process, involving various steps. Known as software development life cycle, these steps include planning, analysis, design, development & implementation, testing and maintenance. These steps go on to create the perfect software for clients. ”

Explain the role of software design principles and software structures in the IT systems development lifecycle

As design moves forward, the development teams begin to generate a tremendous amount of detailed information about the system. Modules, classes, data fields, data structures, forms, reports, methods, subroutines, and tables are all being defined in substantial detail in the design model. The key design tasks are decomposing the application into layers, clients, and servers, distributing the “pieces” across hardware platforms, and defining the physical network and protocols.

System development can generally be thought of having two major components: systems analysis and systems design. In System Analysis more emphasis is given to understanding the details of an existing system or a proposed one and then deciding whether the proposed system is desirable or not and whether the existing system needs improvements. Thus, system analysis is the process of investigating a system, identifying problems, and using the information to recommend improvements to the system. System design is the process of planning a new business system or one to replace or complement an existing system.

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.

The Software Development Life Cycle is a model, which consists of multiple steps or phases. This model is used for the development of software or application. The purpose of SDLC is to make software more efficient and effective. The life cycle typically has six phases. It starts with analysis and design phase, then the implementation/ construction phase, testing phase, release or deployment phase and ends with maintenance phase. The analysis phase determines why the need for the software arose, the deliverables or outcome expected from the software or system and also identifies the various requirements for the development. It is very important to involve users, stakeholders and working engineers in this phase, to ensure that the “Why” criteria is thoroughly fleshed out. A well worked out analysis phase will help developers and architects to successfully work on the given requirements in the design phase. The design phase might also involve building several use cases and building prototypes for users. Design can be logical design, physical design or architectural design. In the construction phase, physical construction is done to complete the software (i.e. programming, hardware, software and so on). The implementation phase turns the design into an actual product. The next phase tests the software for possible vulnerabilities and bugs. This is to ensure that the product is safe from possible security breach. The product is tested in the real world to see if it functions as

Computer system plays an important role in solving human problem in their daily life. There are standard steps in order to develop information system called System Development Life Cycle (SDLC). SDLC is the framework available to build a complete system. There are five phases in SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in Appendix 1).

The software development life cycle is the cycle in which software is developed. It is a process that has been improved upon as programming has expanded and become a bigger part of computers and networking. Programming is necessary in order to enable computers to perform in a desired manner, and those computers rely on that programming as instructions in order to function. Since computers rely on their programming to know how to function, the programming needs to be as efficient and flawless as possible, in order to produce ideal results. The software development life cycle is a tool used to help achieve ideal results.

In software development, there are various types of methods that developers follow in order to produce valuable software. From the many types of methods that exist today, the industry standard that is mostly followed today is the software development lifecycle (SDLC). The SDLC is a process that software development companies utilize in order to design, develop and test software during production. Within the SDLC, there are different test models that developers can utilize based on their business and development requirements. Currently today, the most common models include the waterfall, iterative, spiral and V-model. Regardless of the model that a developer decides to utilize, all the phases will be the same, which would begin with the first step and that is the requirement gathering and analysis phase.
